Some apps go wrong with VPN
We must bear in mind that not all the programs that we have on the computer or mobile are going to need the same resources. Some will need a Connection that has higher bandwidth, while other applications will work without problems even if the Internet speed is very limited.
Just this that we mentioned is what causes some programs not to work when we connect the vpn. They are applications that are going to need a better Internet connection and VPNs normally slow down the connection, cause greater latency and, in general, problems that we would not have if we browsed directly on the network.
For this reason, some programs, such as applications to make video calls, watch streaming videos, or even browsers on occasion, will have difficulty functioning correctly. On the other hand, other programs such as messaging applications such as WhatsApp or email will hardly notice anything since they do not need a large bandwidth to work correctly.
We could also apply this to cloud services or video games. In these cases, they will need a good connection, a high speed, since otherwise they would work in a limited way and we could have problems.
What to do to avoid problems
So what can we do to prevent some programs from not working well with a VPN? You will be able to take into account certain tips that will allow you to improve your connection and thus ensure that those applications have fewer problems to work correctly even if you are using a VPN.
The first and most important thing is choose very well which VPN to use. That is going to be the key for it to work correctly and avoid problems. You will find a lot of options, but not all of them will work well. Especially the ones that are free may have more problems and limitations. Learn very well before installing it.
You should also make sure that the Internet connection is correct. If you use a VPN and connect to a very limited Wi-Fi network, for example, you are more likely to have difficulty navigating. You can always count on wireless repeaters, Mesh or PLC systems that help improve the connection and avoid poor coverage.
On the other hand, keep the equipment in good condition it will help when you use a VPN. It is important that you have the system updated, as well as the VPN, but also that you have security programs that help detect possible problems that may appear and compromise proper functioning.
In short, as you have seen, sometimes there are problems with certain programs when you connect them through a VPN. You can correct this, at least to some extent, if you choose very well which application to use and make it work as well as possible. Even the antivirus could detect the VPN as a threat and that would hinder its operation.
